. Fig. is a similar view showing the application of the gauge forsetting a lower creasingl member. l I Y I Fig. 8 is van enlargeddetail'view of a portiony -of the stock showing the impression formed bythe scoring andn creasing devices.

Usually scoring and-creasing machines of the type to which the presentinvention relates comprise plurality of 'units through j as by setscrews 37.to the bar 23. It will be i927. .si-,ritiirai-*195,1104

which the stock is passed to crease 'andscore the same along thedesiredparallellines. For

lthe purpose of illustration, only one unit is indicated in the machineshown in the drawings. rllhis machine comprises a bar 23 mounted infixed position in the machine and a shaft 24 disposed parallel andadjacent to the bar 23.-V Conveniently, and as herein shown, the frameof the creasing and scoring mechanism may include -a pair of parallelside uprights 25 between which a suitable table (not shown) as well asthe bar 23 are supported, said upright's earryingsuitable bearings inwhich 'the-shaft 24 is journalled. Suitable means are also provided forrotating the shaft 24. As shown Vthe shaft 24 is provided with a drivingpulley 31 to which power from any suitable source may( be appliedthrough a belt (not shown). l

Separately, detachably, and adjustably' mountedgon the bar 23 larecreasing and scoring devices corresponding in number and arfrangementtoV the scored and creased lines of` the yblanlr.-` Preferably,asV shown, the creasing devices 32 and scoring devices'33 comprise diskslor wheelsrotatably mounted in earri'ers`34 adjustable as fby adjustingscrews 35am holders 36 detachably secured seen that the holders 36` withtheir creasing Vand scoring devices can be applied at willto the bar 23or removel` therefroin or adjusted therealong transversely of themachine in accordance with therequirements ofthe w'orlr.r i The creasingdevices 32 have peripheral rse surfaces shaped to` cooperate withcoinple'- .-inentary surfaces on the shaft 24 tocrease or score thestock S asindicated'- at c and s re-V spectively in Fig'. 8. To this endand as most elearly'show'n in Fig,V 7 the creasing wheel or disk 32 isformed with a peripheral groovel which receives a rib V38 on the shaft24. Each undercut 0roevei4()a in the -sliaft wlierebv' c: i .l

said ringo-r collar may be adjusted along.

`rib 38 is formed on a ring or collar 39 adjustlsaid shaft in accordancewith the adjustnient ofA the complementary' creasing wheel on the bar23. Preferably the ring or collar `is split to facilitate itsapplicationto and re- -inoval from the shaft, andtheftwo Vsections 'aresecured in assembled relation aboutthe shaft by bolts or screws 41.4

. @Ehe-bar 23, whileoccupying Ia opera-g tive position iii the machine,is preferably pivotally mounted therein to turn about a fixedvtransverse axis yinto operative or 1noperative position.. As showmsaidbar is yin Fig. l.

(vided.

formed With trunnions 43 suitably jour* nailed in the upiights and isprovided With an operating handle .44, whereby it may be readily turnedupon said trunnions into the operative position shownin Figs. 3, 4 and 7or into the inverted orY setting positionY shown The handle 44cooperates Vwith a fixed segment 45 carried by one of the side uprights25 and'is provided With apivoted manually operated latch 46cooperatingwith openings 47 in said segment, whereby the bar may belocked in either position.. When the bar is in operative position, thecreasing and scoring devices thereon are broughtinto cooperativerelationship With the complementary surfaces on the shaft 24, and whensaid bar is turned into its inverted position,

said creasing and scoring devices are brought into a position adjacentthe top of themachine Where they can be conveniently applied to,removedv from, or adjusted on the barl For the purpose of facilitatingthe setting of the creasing and scoring devices in their proper relativepositions en the bar 23 and shaft k24, the collocating instrument mostclearly shown in Figs. l and 2 may be pro- As shown, said instrumentcomprises fa vbar 43 extending transversely across the -m'achine andcarried at its ends by slides 49 7 In accordance With one feature of thein-v vention the co-operating creasing members are provided with pointsequidistant from or bearing soin-e other definite relationvto thecentral plane of the effective ci'easii'ig portion thereof so that saidcentral vplanes may be alinedaccurately and readily Without specialskill or experience by a gauge. In the `enibodiment ofv the .inventionillustrated the radialv face 60 of the creasing diskor Wheel 32 -isspaced from the central plane of the effective creasing portion of saidWheel a( distance equal to or Which bears a definite relation to thedistance which the radial face 61 on the collar 39 is spaced from thecentral plane of the effective creasing portion vof the riby 38 Yon thecollar 39.V

A gauge G is provided which is adapted to embrace or fit vover the edgeof onel of the It will be seen that the cooperatingcreasing members. Inthe form illustrated, this gauge coi'nprises two members having faces 62'and 63 spaced apart to fit over the creasing Wheel -or disk 32 andcon.n nected by a portion 64 having a part, such as hair line impressionG5, thereon located in a plane having. adefinite predetermined rela-Ytion to one of the faces 62 and 63 when engaging a predetermined surfaceof the disk 32 so that this line will lie in the central plane of theeffective'creasing portion of thedi'sl. In order that they gauge may beplaced upon the disk and held securely thereon during the adjusting andsetting operationthe gauge is provided with a threaded opening 66 to'`receivea clamping screw 67. In order thatV the central plane of theeffective ereasingportion of the rib 38 on the collar 39'may be aline'dWith the central planeof the effective creasing portion of the disk 32,one of the faces of the Vgauge is provided with a projection 63 having aface :which is adapted to engage a predetermined point or surface uponthe collar 39, herein shown as a radial face 6l, When the gauge isfitted over the edge of the disk 32 to bring the central planes oftheeffective creasing portions of the rib 38 andV disk 32 into a commonplane.

Vhen it is desired to adjust or set the cooperating creasing members,the bar 23 is turned to the inverted or inoperative posit-ion shown inFigs. l and 2. The scale is then turned upon its hinge 54 into proximityWith the creasing members. The gauge G-isthen fitted over the edge ofoneof the creasing members upon the bar 23 With the hair line in thecentral plane ofthe effective creasing portion thereof. The creasinglmember is then adjusted to bring the hair line ata desired point uponthe scale. Without changing its relation to the adjusted creasingmember, the gauge is then brought to a'position Within the path ofadjustment of the creasing member cooperatingl With the adjustedcreasing member and thereafter predetermined points or surfaces -of the'gauge and cooperating creasing member are brought-into engagementthereby aligning the central planesY of the effective portions' of thetivol creasing n members. In this manner theV various coopyeratingcreasing members are adjusted upon the machine relative to each other asdesired. V
